not to hard to do. put the car on jack stands, all four corners, use a floor jack to support the trans, put a piece of plywood between the jack and pan. Pull drive shaft, disconect tranny lines and shift cable, speedo cable, electrical harness. After that its just the converter to flywheel bolts, bellhousing bolts (helps to have a long extension for those) and crossmember. You might need to support the rear of the motor to keep it from rocking to the back, I believe I didn't when I changed my converter.
That is the basics of it, I'm sure others will have more to add.
Also, you might get a few more replies if you post in the "general section" or "transmission section".
Good luck.
